Siltstone Wines sources Oregon Pinot noir and Pinot gris from Guadalupe, a 40-acre vineyard owned by Jim Stonebridge and Kathleen Boeve and currently leased to Ken Wright Cellars. Â Wine grapes were first planted in 1989 and Vinetenders has managed the site since then, coordinating the design, planting and daily management.
Guadalupe Vineyard is located in the Dundee Hills AVA.  However,the soils are not typical of this appellation.  The soils at Guadalupe are marine sedimentary, mainly silty and sandy loams, while those found in the Dundee Hills are heavier clay loams.  Spaced at 7' x 5', it is planted to the Wädenswil, 777 and Pommard clones.  The elevation is between 350'-450', and produces dark colored, intensely flavored fruit.Â
